What shade number is carbon-arc welding?

• A. 12
• B. 13
• C. 14
• D. 15

Answer: (C)

Shade selection for welding is determined by how bright the arc is and how much UV and IR radiation it emits. Carbon-arc welding uses a very intense arc, so you need a darker protective filter to shield the eyes while still allowing enough visibility to work safely. That makes a shade of 14 the appropriate choice for carbon-arc welding. Using a lighter shade would not provide sufficient protection from the bright arc, while a shade that’s too dark would make it hard to see the weld and control the process. In comparison, many other welding processes can use lighter shades because their arcs aren’t as intense.
